WF003 Hex Nuts are used with bolts and screws for connecting and securing parts. The 1-Type Hex Nuts in WF003 are widely applied. C-Grade nuts are used on machinery, equipment, or structures with rough surfaces and low precision requirements; A-Grade and B-Grade nuts are used on machinery, equipment, or structures with smooth surfaces and high precision requirements.

The high-performance WF003 hex nut consists of the nut body and the base. The nut body is hexagonal prismatic, featuring a circular through-hole in the middle, which is threaded. One side of the nut body has a boss, and the opposing side also has a boss. The bosses on the product are centrally located on the nut body side, shaped cylindrically, and are formed together with the nut body in a single processing step.
